T.1-26 No Partial GALL item IV.D1.1-f and IV.D1.1.l address loss of preload due to stress relaxation of the secondary side bolting (IV.D1.1.7) and cracking due to stress corrosion cracking of primary bolting (IV.D1.1.11) as a result of boric acid exposure respectively. The sub-component AMR result is consistent with the identified GALL items with respect to material, environment, aging effects requiring management as clarified, and credited aging management program as clarified. The aging effects that the GALL items refer to (loss of preload / crack initiation and growth) are considered "loss of mechanical closure integrity" at VCSNS. However, the corresponding mechanisms that the GALL items refer to are considered to result in the above aging effect at VCSNS. Additionally, while the GALL items differentiate between secondary side bolting (loss of preload) and primary side bolting (cracking), VCSNS conservatively considered all Steam Generator closure bolting to be susceptible to both mechanisms. Furthermore, SCC is only applicable to high strength bolts (yield strengths > 150ksi). SA-193 and 194 closure material utilized at VCSNS typcially has a yield strength of 105 ksi and is not strictly high strength. However, the ISI Plan, as it applies to Steam Generator closure bolting, rather than a separate "Bolting Intergrity" program as specified by the GALL items (IV.D1.1-f and IV.D1.1-l), is credited for management of both loss of preload and SCC in primary and secondary side closure material.

Also, GALL item IV.D1.3-a addressed flow-accelerated corrosion of feedwater inlet rings in CE system 80 generators (also carbon steel).

Partial GALL item IV.D1.2-b addresses cracking of Alloy 600 tubes and sleeves.

Certain aging effects not addressed for this GALL item are also managed by the credited programs (crevice and pitting corrosion and flaw growth). Additionally, the credited programs, as they are applied to Class 1 components, are consistent with GALL Chapter IX programs (XI.M2 and XI.M1 respectively), whereas the GALL item identifies programs that are focused on the tubes instead of secondary side outlet nozzles. As such, the GALL recommendation for effectiveness verification is not applicable to the secondary side outlet nozzle.

GALL item IV.D1.2-h (IV.D1.2.2) addresses tube supports and corresponds with regard to material and environment, but differs with respect to aging mechanism. Also, an aging effect (SCC of nickel-based portions) not addressed by the GALL item are also managed by the credited program. Additionally, IN 90-04, which is referenced for the GALL item as the basis for enhanced detection of aging effects in the shell, addressed flaw growth at girth welds due to service loading. The IN contains only general indication that pits on the surface served as crack initiation sites, and not that pitting corrosion resulted in sufficient degradation to cause loss of component function. Lastly, the tube bundle wrapper support portions of the Steam Generators are not strictly necessary for the Steam Generator(s) to perform the required function of pressure boundary, throttling or heat transfer. The wrapper support portions were, however, conservatively subjected to AMR.
